Application filed June 18, 1912.

To all whom it may concern:

-Be it known that 1, James F. MCELROY, a citizen of the United States, residing at Albany, county of Albany, State of New York, have invented certain new and useful lmprovements in Steam-Heating Systems, the following being a full, clear, and exact disclosure of the one form of my invention I which I at present deem prererable.

For a detailed description of the present form of my invention, reference may be had to the following specification and to the accompanying drawings, which illustrate my invention. wherein Figure 1 is a perspective showing the fundamental principle of my system; Figs. 2 and 3 are fragmentary detail. views showing the diiierent conditions of the shift valve; Figs. 4 to 9 inclusive are detail views showing in section and elevation the practical construction and arrangement of vapor and pressure traps suitable for my system; Fig. 10 is a perspective view, and Figs. 11 and 12 are fragmentary detail views showing the mode of splitting my series-multiple system for two sides of a car; Figs. 13, 1d, 15 are views similar to Figs. 10, 11 and 12 showing a split and duplicated arrangement of my series-multiple system for larger and more flexible heating requirements.

My system is designed to operate either as a vapor or pressure system and the radiator pipes therefor are divided into sections which are connected in series with each other for vapor heating and in multiple for pressure heating. 1 also place the pressure trap at the point of junction of the two pipe sections which are both connected with the screen chamber of the trap, whereby under the series arrangement the steam will sweep through that chamber and clear the dirt therefrom. which would tend to accumulate therein under the multiple arrangements. For lesser heating requirements. as in modern cars, I split the piping, placing the respective pipe-sections on opposite sides of the car, while for greater heating requirements, as in steel cars, I both split and duplicate the piping for securing not only a greater total of heating effect,

but also more degrees of regulation by changing from vapor to pressure conditions in the several sections.

source of steam supply. is shown at T. The radiator piping is divided into two parts or sections,-the pipes in the first section being marked a and those in. the second section 'heing marked Z). The inlet from train pipe T to the radiator is by the lead pipe 1 which conducts the steam to the vapor trap (containing the inlet valve controlled by the trap) from which the pipe 2 leads to the first pipe section comprising pipes a and the pipe 2 (communicating with the thermostat-chamber of the trap) leads to the second section comprising the pipes b. The two sections are joined at the pressure trap P to which they are c nnected by'the respective pipes 4 and 4 It should be understood that the short section of pipe marked 5 between train pipe T and the. pressure trap P is not a part of the circulating system but merely a pipe for the local external heating of the trap by the train pipe. These two pipes 4'"- and 4 enter the trap on opposite sides-of the screen chamber of the trap and, when the two sections are in series, the flow of steam through the chamber will sweep out the dirt which tends to accumulate therein when the sections are in multiple and the trap forms the terminal of the system. Thus, Figs. 6, 7 and 9 show the pressure trap in detail, the screen-chamber thereof being shown at Gr and. the screen at S. The thermostat M of the trap (it is contained in an open cage ll from which water can escapelwi operate the outlet valve K by means of the stem R in the usual manner to control the outflow of water of condensation from the chamber G to the thermostat and the outer air, whenever the system is set "for pressure operation. The steam (under vapor conditions) will enter chamber G by pipe 4' and depart therefrom by pipe 4:.

In Figs. 4 audio are shown the vapor trap i r V wherein, as is well known, the outflow of water of condensation from the radiator "ooth sets will be put under pressure condi ator divided into distinct sections, a supply pipe, means for selectively connecting said sections with said supply pipe in series or in multiple, and automatic means for vary ing the pressure in said setions to conform to the connection selected.
